ABSTRACT:
An improved trap fitting assembly (F.sub.1, F.sub.2) which prevents the spread of fire and smoke through a floor (100,200) of a building is described. The fitting uses a flammable coupling (10, 30) and a non-flammable sleeve (14, 32) inside the coupling with an extension (14b; 32b) from a lower most portion of the floor which is connected to a non-flammable J-pipe (16, 34). In use the J-pipe contains water (101, 201) at a level (L-L) prevents the fire and smoke from going through the floor. The trap fitting is preferably adapted for a floor drain outlet (11) or tub (203).
